odd carb thing

ok working on a base *** 84 12a with a/c and thats it not even a map light. any way to the question. just slaped a newer motor in this 84 and she idles and revs GREAT but under a load when you floor it it *****... starts jerking, wont rev, loses rpms and will die. now if i just add a little gas at a time and dont floor it she does fine and will rev up to 6-6500( dont want to rev new motor to high yet) but as soon as i stomp on it , it craps out again... HELP
